Question

What is r hat in Coulomb's law?

Answer 1

Answer:

The distance between the two charges is "r." The "r" actually stands for "radius of separation" but you just need to know it is a distance. The "q1" and "q2" are values for the amount of charge in each of the particles. Scientists use Coulombs as units to measure charge.

Answer 2

Answer:

Explanation:

Coulomb's Law is a model for the forces between two charged particles.

If the two charges have opposite signs, the direction of the force will be in the opposite direction as the r-hat vector.

If both charges have the same sign, then this force will be pushing the two charges away from each other.
